I have come across a problem where for a user , Blackberry Address book and lotus notes address book does not seem to synchronize as both show different . I have already asked the user to turn off and tun on wireless activation , turn off and turn on device etc but unfortunately it does not seem to help. Is there something else that need to be checked . Please let me know.

first synchronize the address book in notes. im on a BEZ 4 and Notes 7.0.1,
Open your notes inbox - select - ACTIONS - OTHER - SYNCHRONIZE ADDRESS BOOK in the run agent box. It takes a while for the sync to complete.

If the user already does this and it still wont sync, then delete the Desktop [Sync] service book on the blackberry and have the BEZ resend it to the handheld.
